These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight. You must be logged in to sign up for monitoring You must be logged in to astmm up for subscription.

This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system. Please choose number of devices you want to open the document on.

Xstm, for larger sized excavations, Test Method D is preferred. The values given in parentheses are for information only.

ASTM D4914/D4914M – 16

The material being tested should have sufficient cohesion or particle interlocking to maintain stable sides during excavation of the test pit and through completion of this test. Username or password invalid. For specific hazards statements, see Sections 7 and A1. While the equipment illustrated in these test methods is used for volumes less than 0.

ASTM D4914

The material being tested should have sufficient cohesion or particle interlocking to maintain stable sides during excavation of the test pit and through completion of this test. While the equipment illustrated in these test methods is used for volumes less than 0. Link to Active This link will always route to the current Active version of the standard.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Combining values from the two systems may result in non-conformance with the standard. For Test Methods D and D only, the unit weight determined in the laboratory compaction test may be corrected for larger particle sizes in accordance with, and subject to the limitations of Practice D Link to Active This link will always route to the current Active version of the standard.

It is undesirable to combine the use of two separate systems within a single standard.

ASTM D Standard

The accuracy of the test methods may be affected for materials that d9414 easily or that may undergo volume change in the excavated hole from standing or walking near the hole during the test. It should also be firm enough not to deform or slough due to the minor pressures exerted in digging the hole and pouring the sand.

The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s. Continue shopping Proceed to checkout. Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. Then the material is considered to consist of two fractions, or portions.

The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s. Test Method A can also be used to determine percent compaction or percent relative density when the maximum particle size present in the in-place material being tested does not exceed the maximum particle size allowed in the laboratory compaction test refer to Test Methods D, D, D, and D The material from the in-place unit weight test is physically divided into a control fraction and an oversize fraction based on a designated sieve size.

However, conversions are given in the SI system. Historical Version s – view previous versions of standard. In general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in.

In general, the materials tested would have a maximum particle size of 3 to 5 in. The printed version is available at half price when you buy the electronic version. Test Method A can also be used to determine percent compaction or percent relative density when the maximum particle size present in the in-place material being tested does not exceed the maximum particle size allowed in the laboratory compaction test refer to Test Methods DDDand D It is scientifically undesirable to combine the use of two separate systems within a single standard.

Do not show this again. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

For construction control, these test methods are often used as the bases for acceptance of material compacted to a specified density or to a percentage of a maximum unit weight astj by a standard laboratory test method such as determined from Test Method D or Dsubject to the limitations discussed in 1.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Then the material is considered to consist of two fractions, or portions. It should also be firm enough not to deform or slough due to the minor pressures exerted in digging the hole and pouring the sand.

However, for larger sized excavations, Test Method D is preferred. In addition they are representative of the significant digits that generally should be retained.

Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing. While the equipment illustrated in these test methods is used for volumes less than 1 ft 0. Other relevant standards DS
